Abstract: A novel max-heap overlay tree is constructed as a multicasting scheme, based on bandwidth-latency-products' Node Gain Scores (NGSs) of individual nodes. These NGSs, used as a basis for shaping the overlay tree, are determined by respective bandwidth-latency-products (BLPs). Each node's NGS is a synergy of the discrepancy ratio of the bandwidth requested, Br, with respect to the estimated available bandwidth (BDR), and the latency discrepancy ratio between the nodes and the source node, Ba (LDR). It is proposed that each node to be positioned according to NGSs which is a function of four parameters – available bandwidth, Ba; requested bandwidth, Br; proposed node latency to its prospective parent, Lp; and suggested best latency as advised by the source node, Lb. BDR and LDR with the weights of  and =(C-), respectively, are realized. Arbitrarily chosen, 0 ≤ a ≤ C and  = C - a ensure that the NGSs, used as node IDs, maintain!
uniqueness and balance between BDR and LDR. The constant C is, hence, chosen depending on unique Node_IDs desired. A max-heap-form tree is constructed with an assumption that all the nodes possess NGSs less than the source node. Load balance is introduced by making sure that children of each level's siblings are evenly distributed. The records of the pair-wise available bandwidths as measured by a pathChirp scheme are maintained. Evaluation as compared to other schemes - BASE, TBCP, and HMTP - has been done. With moderate sized overlay groups, the NGS scheme performs better in terms of packet delivery ratio; maximum link stress; control overhead; and end-to-end delays.
